Meg, over at Unravelling, suggested we celebrate "the humble spool".
Forgetting to take a picture at the studio yesterday, I was saved by today's flea-market find:
Nice and smooth, it has the exit hole lined with bone, which shows it has been used a lot.
The spool was a bonus :-) It holds a doubled fine cotton, 24/2 at a guess.
The spool itself is of ordinary brown paper, not cut to the "prescribed" oval.
Otherwise, my spool box looks like Cally's, except 95% of the spools are paper. Using paper you never run out of spools, or even need to empty them... and, like Meg, I have some that may be 10 years or older (the paper, I mean! - well, maybe one or two hold yarn that old too...)
